Hi Julie, In Seneca County birth and death records from the assessor's records are recorded in volumes in the Probate Court building at Market and Jefferson Streets, near the Courthouse. These records start in 1867 (I think) and go until 1908, when birth and death certificates became required in Ohio. The records at the Probate Court are not complete, and the information is sketchy. Rarely are the parents names given in the death records, even for infants. The information is on one line per record, in a book with preprinted information columns. The birth and death certificates, beginning in 1908, are at the County Health Department. They recently moved, and are now on Washington Street in the area of the Courthouse. There is much more information to be found on these certificates than on the earlier records. Birth and death certificates in Ohio are filed with the state, with a copy kept at the county health department. Ohio death certificates (not birth certificates) from 1908 to 1945 are available on microfilm at the Ohio Historical Society in Columbus, where copies can be made for 25 cents. An index of these certificates is also available. Part of the index (for the years 1913-1937) is available on line at: http://www.ohiohistory.org/resource/statearc/ It saves time to check the index on line before going to Columbus. There are usually lines to use the fiche index at the OHS library. If you already know the year and certificate number you can go right to the microfilm. I hope this helps. Don Rogier
